Problem

A capacitor

C_{1} = 2\,\mu\text{F}

is charged to a potential difference of

V_{1} = 20\,\text{V}

. It is then isolated and connected to an uncharged capacitor

C_{2} = 3\,\mu\text{F}

through a switch

S

. Calculate the final common potential and the heat energy dissipated in the circuit after the switch is closed.
